An empirical model based on logistic equation coupled with gel polarization/film mathematical model based on cake filtration theory, have been developed in the present study. Unlike the factors needed to be determined in convection–diffusion model, the factors in this empirical model were easier to achieve. In this paper, the estimation of gel polarization process in two different UF processes (stirred...
The high-molecular-weight anionic polyacrylamide (6880kDa) adsorption related fouling of a virgin PVDF membrane (OM) and a modified PVDF membrane (MM) were investigated via analysis of particle size distribution, structure of membranes, influencing factors, SEM, and ATR-FTIR. The purpose of this paper is to better understand the mass transport characteristics in the adsorption system of APAM and two...
